Standard 1: Number, Number Sense and Operations

Resources

Benchmark

Indicator

  

A.   Represent and compare numbers less than 0 through familiar applications and extending the number line.

1.   Construct and compare numbers greater than and less            than 0 by extending the number line and using familiar     applications (e.g., temperature, owing money).

  

B.   Compare, order and convert among factors, decimals and     percents.

D.   Use models and pictures to relate concepts of ratio, proportion and percent.

1.       Use models and visual representation to develop the concept

of   ratio as part-to-part and part-to-whole and the concept of percent as part-to-whole. For example:

    Part-to-part 3:2 red marbles: green marbles

    Part-to-whole 3/5 red marbles; all marbles

2.   Use various forms of “one” to demonstrate the equivalence of    fractions.

3.   Identify and generate equivalent forms of fractions, decimals,        and percents.

  

E.   Use order of operations, including use of parenthesis and             exponents to solve multi-step problems and verify and interpret      the results.

1.   Identify and use relationships between operations to solve         problems.

2.   Use order of operations, including use of parentheses, to simplify numerical expressions.

  

F.   Apply number system properties when performing         computations.

1.   Use commutative, associative, distributive, identity, and    inverse properties to simplify and perform computations.

  

G.  Apply and explain the use of prime factorizations, common factors, and common multiples in problem situations.

G2. Use strategies to identify the greatest common factor (GCF)      and the least common multiples (LCM) of 2 or 3 numbers.

1.   Recognize and identify perfect squares and their roots, using            a factor tree.

  

H.   Use and analyze the steps in standards and non-standard     algorithms for computing with fractions, decimals and integers.

1.   Determine and use common denominators multiplying by 1             (e.g., 5/5 to add and subtract fractions).

2.   Explain how place value is related to addition and       subtraction of decimals (e.g., 0.2 + 0.14; the two tenths is            added to the one tenth because they are both tenths) and           master addition and subtraction of decimals.

  

I.    Use a variety of strategies, including proportional reasoning to             estimate, compute, solve and explain solutions to problems       involving integers, fractions, decimals and percents.

1.   Round decimals to a given place value and round fractions   (including mixed numbers) to the nearest half.

2.   Construct and use physical models, points of reference, and    equivalent forms to add and subtract commonly used            fractions with like and unlike denominators and decimals.

3.   Estimate the results of computations involving whole    numbers, fractions and decimals, using a variety of           strategies.
